FOOT-MEASURING DEVICE.

Application area Marcil 1,1926. semi No. 91,402.

This invention relates to a4 devicerfor measuring feet, lasts and the like. Such measurements are especially use'liul in the manufacture of footwear. In the practical measurements ot feet, the following dimensions should be'determined: The length ot,

to provide a device ot the character described which has ya wide range of eXpansion, requires a minimum ot Work in adjustment, may be quickly operated, is compact, simple in structure and economical to construct. Another object 01"' this invention is to provide a device of the character described which -may be arranged to measure both feet and lasts.

These objects together lwith other objects and corresponding` accomplishments are ob tainedrby means or" the embodiment of my invention illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation ot my device partly in section showing it as applied to a toot; Fig. 2 is a plan view with a portion o1 the top ot' the device brolren away; Fig. 3 is a section as seenvon the line 3-3 ot Fig. 1; and Fig. 4 is a fragment oitn a measuring tape.

Referring more particularly to the drawi ing a base 5 is provided, it being preferably rectangular in plan and having a* cavity G. A cover 7 is mounted upon the base and provided with a longitudinally extending slot 8, thereby providing` a slideway. At one end ot the base is a heel stopV 9 tiXed in position and having an upright abutment plate 10 with which the heel of a toot or last may be engaged. Slidably mounted upon the base is a body 11 having a slide block 12 depending from the under side and extending through the slot 8. Mounted upon the body is a toe abutment plate 18. This plate is secured' to the body by means ot a set screw 111 extending through an elongated bolt khole 15, so that the position oft the plate 13 kupon the body may be adjusted.

Marked upon the cover at the slot 8 is a scale S for showing the length or distance between the heel plate 10 and the body ot the toe plate 11 in terms ol' the usual foot sizes. Thus, a toot length gage is provided.

The toe plate body 11 is secured or connected to a pantograph 16 mounted in the cavity of the base and lined in position to the base at the other end as indicated by 17. Thus, on sliding the toe stop back and forth upon the base, the pantograph will be expand-ed and contracted. Secured to the pantograph and extending through slot 8 is a pin 18. This pin is located upon the pantograph at a position proportioned to the position'of the ball of the foot. This pantograph and pin provide a proportional movement. Secured to the pin 18 isa tape 19 having an eye 20. The tape is arranged so that one end thereof may be passed through Vthe eye and the transverse peripheral di-` mension of a Ybody thereby indicated as best shown in Figs. 1 and 3. `Extending through the slot 8 is another pin 21 having secured Y thereto a tape 22 provided with an eye 23. The pin 21 is located at the waist of the foot. A third pin 24 extends through the slot and is secured to the pantograph, it being provided with a tape 25 and an eye 2G. Pin 24: is located at the instep and is for the purpose ot measuring that portion of the foot. It will be noted that the position of pins 18, 21, and 24, are changed with the movemont ofthe pantograph and the movement- Vof the toe stop, but theirprelative positions proportional to the distance between the heel and toe stops remain unchanged.`

A toot tobe measured is placed upon the base with its heel abutting the heel stop or abutment plate 10. moved to engage the toe, and the length orA size ot the 'oot may be read from the scale S on the base. Movement of the toe stop will have caused the ball, waist, and instep tapes to be properly positioned. The tapes are then passed around thel toot, as indicated in Fig. 1 tor the supplementary measurements.

In F ig. l I have shown a scale which is useful for measuring with the tape. The s ale is divided into eighths of inches. The

The toe stop is then first eighth is marked l, the second 2, and so on, the seventh being marked 7 the eighth is marked lO, the ninth 11, and so on; the sixteenth is marked 20, and the twenty-fourth is marked 30. rIhe scale is used in the following manner. The tens in the numbers indicate inches, and the units the number of eighths. For illustration, l5 indicates 1% inches, twenty-seven 27/8 inches, and thirty-three would indicate 33/3 inches. Such a scale is convenient tor the purpose of reading.

It is obvious that the units of length used for measurements is immaterial to the in vention. It is also 4obvious that the device is not limited to measurement ot feet. The lasts for a given size of foot are longer than the foot. In order to make the measuring device adaptable for lasts for comparison of measurements to the foot, the screw la is loosened and the plate 13 is moved upon the body so that the difference in lengths between the foot andthe last will not change the tape locations already determined by the toot.

IlVhat I claim is:

l. A measuring device comprising an expansible toot length gage including a pantograph, and supplementary measuring devices located on said pantograph whereby said supplementary devices will be moved proportional to the movement of said gage.

2. A measuring device comprising an expansible toot length gage including` a pantograph, and supplementarv measuring devices located on said pantograph, each of said supplementary devices comprising a tape for embracing the toot transversely.

3. A toot measuring device comprising an expansible foot length gage including front and rear abutments, a pantograph comprising a jointed parallelogram connecting said abutments, and Vsupplementary measuring devices mounted on said pantograph whereby said supplementary devices will be located proportional to the distance between said abutments.

d. A measuring device comprising an expansible 'foot length gage including front and rear abutments, a pantograph comprising a jointed parallelogram connecting said abutments, and supplementary measuring devices mounted on said pantograph where- `by said supplementary devices will be lo.

cated proportional to the distance between said abutments, each of said supplementary measuring devices comprising a tape embracing the foot transversely.

5. A ioot measuring device comprising a a base having a slideway, a pantograph mounted in said slideway with one end fixed, a heel stop secured at the point of fixture oit' said pantograph, a toe stop secured to the other ond of said pantograph and supple; mentary measuring devices mounted on said pantograph whereby said supplementary devices will be located proportional to the position of said toe stop.

6. A toot measuring device comprising a base having a slideway therein, a pantograph mounted in said slideway with one end fixed, a heel stop secured at the point of Fixture ot said pantograph, a toe stop secured to the other end of said pantograph, and supplementary measuring devices mounted on said pantogra-ph whereby said supplementary devices will be moved proportional to the movement of said toe stop, each o' said supplementary measuring devices comprising a tape for embracing the foot transversely.

7. A foot measuring device comprising a base having a slideway therein, a pantograph mounted in said wayV with one end lixed, a heel stop secured atI the point of lixture or said pantograph, a toe stop comprising a body secured to the other end of said pantograph and an upright abutment adjustable lengthwise of said body, and supplementary measuring devices mounted on said pantograph, whereby said supplementary devices will be moved proportional to the movement ot said toe stop. A

8. A toot measuring device comprising a base having a slideway therein, a pantograph mounted in said way with one endy fixed, a heel stop secured at the point of tixture of said pantograph, a toe stop comprising a body secured to the other end of said pantograph and an vupright abutment adj ustable lengthwise on said body, and supplementary measuring devices mounted on said pantograph whereby said supplementary devices will be movedproportional to the movement of said toe stop, each ot said supplementary devices comprising a tape for embracing the toot transverse. Y

In witness that I claim the foregoing I have hereunto subscribed my name this 18th day of February, 1926.
